Virgin Galactic has achieved another milestone in its push to become the world’s first private commercial spaceline with the unveiling of the WhiteKnightTwo (WK2) carrier aircraft. Built at the Scaled Composites facility in Mojave, California, the twin fuselage WK2 is a formidable engineering feat. It is the world’s largest all carbon composite aircraft and the main wing, which spans 140 ft, is the longest single carbon composite aviation component ever built. Christened “EVE” in honor of Sir Richard Branson's mother, the aircraft can can fly across the US non-stop and reach altitudes of 50,000 ft - the height from which SpaceShipTwo (SS2) will be air launched.
